wireproto: add config knob for http header length limit

Well-behaved Mercurial clients will respect the httpheader capability by not
sending http headers longer than the given limit in bytes. The limit is
currently hard-coded at 1024 bytes, a safe value for any web server.

Since parsing headers is a notable factor in web server performance, tuning
header size can nontrivially improve performance for request-heavy operations
(eg. obsolete marker negotiation). Exposing the maximum header length limit
as a configuration setting is a simple way to enable such tuning.

from mercurial import util

def makedate():
    return 0, 0
def getuser():
    return 'bob'

# mock the date and user apis so the output is always the same
def uisetup(ui):
    util.makedate = makedate
    util.getuser = getuser
